After five days of testimony interspersed with numerous bizarre behind-the-scenes distractions, attorneys ran out of questions Thursday for a patient who has accused once-prominent San Antonio physician Calvin Day of sexual assault.

Prosecutors rested their case soon after the woman, a personal trainer who said she was assaulted while visiting the dermatologist's office on a Sunday morning in August 2010, left the witness stand.

Meanwhile, prosecutors have rehashed an issue already deemed moot by state District Judge Ron Rangel — providing three sworn affidavits from people who said they were with Day and District Attorney Susan Reed in Las Vegas seven years ago.

Before the trial began last week, Day's attorney's asked that Reed's office be disqualified from prosecuting the case based on the defendant's claim the two had a drunken one-night stand there in January 2006. Reed, also a former patient of Day's, is pursuing “over-the-top” prosecution of Day because she is a “jilted lover,” said the defense's request, which also included results from a polygraph test.

Reed adamantly denied the allegations, but she didn't get to call witnesses to rebut the claim under oath because the judge ruled against the defense immediately after Day took the stand for the pretrial hearing.

“I have read in the newspaper that Calvin Day says he had a sexual encounter with Susan after our dinner together. This is absolutely false and impossible,” Reed friend Barbara Montemayor said in a statement given at the district attorney's office.

The three witnesses described the weekend Vegas trip as a “family event” in which three mothers brought their children to celebrate the 21st birthday of Travis Reed, the district attorney's son. The Days were not part of the group, but everyone met for dinner at the Wynn hotel and casino because Day's wife was friends with group member Yoli Anderson, the documents say.

“When our group left the Wynn, Calvin and Regina Day stayed behind at their hotel, the Wynn,” Anderson noted. “The six of us in our group (including Reed) took taxi cabs back to the Luxor.”

The Luxor is one of the most distinctive hotels on the Las Vegas Strip because it is shaped like a pyramid, they noted. While Day was on the witness stand last week, prosecutors repeatedly asked him at what hotel the alleged tryst occurred. He responded each time that he couldn't remember because of the passage of time and because he was intoxicated.

In her statement submitted to the judge, Anderson described Day as “a fanatical, obsessive compulsive, manipulative, deceitful and ruthless person.” Anderson's daughter, Chrissy Anderson Labatt, expressed similar sentiments, referring to him as sick, “capable of saying anything” and having destroyed his family.

“Calvin Day did not pay any particular attention to Susan Reed,” Labatt said of the dinner. “He was with his wife and spending time with her. Likewise, Susan Reed did not pay particular attention to Calvin Day.

“I think she was interested in seeing the new hotel but was not excited about having dinner with the Days.”

Day, 61, could face up to 20 years in prison if jurors find him guilty of the sexual assault of his patient. Another charge involving another patient is pending, and still other former patients and employees have alleged improper interactions of a sexual nature, according to court documents.

After Day's accuser left the witness stand Thursday, defense attorney Jay Norton called Monica Rivera, the defendant's former secretary. Although Day didn't see patients on Sundays, it was common practice for the two to arrive at the office at 5 a.m. on Sundays to catch up on work, she said.

Rivera knew the patient who would later become Day's accuser was coming in that morning, but she never saw her, she said. She heard no screams or nervous voices that morning, and later on she noticed nothing unusual about Day's attitude or demeanor, Rivera testified.

During questioning from prosecutors, Rivera acknowledged that employees never bothered Day in his “bat cave” — a secluded area of the office where the assault is alleged to have occurred.
